MACHINE F-OR CUTTING MEAT.

SPECIFICATION forming part of Letters Patent No. 287,360, dated October23, 1883.

Application filed April 12, 1883. (N0 model.)

To all whom, it may concern.-

Be it known that I, WILLIAM G. BELL, a.

citizen of the United States, residing at Boschines; and I do herebydeclare that the same are fully described in the following specificaftion and illustrated in the accompanying draw- I ings.

ence being had to the accompanying drawings, where- Figure 1 representsa front elevation of my; Fig. 2 represents a con tral longitudinalsection of it; and Fig. 3 repi resents a cross-section 011 the line A13, shown in Fig. 2. Fig. 4 represents a bottom view of Fig. 5represents in front and improved machine.

the machine. side elevation the lower meat-expeller, shown detached fromits vertical shaft. Fig. 6 represents in plan and section one of thestationary cutters.

This invention relates to improvements in I meat-cutting machines forcutting sausage. meat, and it is carried out as follows, refer- Fig. 7represents in plan and section one of the rotary cutters, (shown asdetached from the vertical shaft.) Fig. .8 represents a plan view of therotary perforated diaphragm; and Fig. El represents a detail sectionalView, showing the adjustable shearingknives and means for securing themin positions above and below the perforated diaphragm.

Similar letters refer to similar parts wherever they occur on thedifferent parts repref= sented by the drawings.

Thls invention relates to improvements on the machine described inpatent granted to me 1 February 27 1883, No. 273,200, and, like said 3patent, it has a vertical cylinder, a, provided with suitable cars, a a,by means of which and bolts a a it is secured to the standard or frameI).

a is the upper mouth or funnel, through which the meat that is to becutis introduced into the cylinder a.

at a a are the longitudinal recesses or pockets of cylinder a for thereception of the cutters c a, each one of which is riveted to itsdivision-block c, as shown in Fig. 6. By making the cutters anddividing-blocks of one piece, or united together, lesssingle pieces haveto be manipulated in placing the cutters in the cylinder, and accuracyis obtained in getting the proper thickness of block and cutter, so asto pass properly between the rotary cutters.

Each series of cutters c is located on a spindle, d, which projectsthrough a perforation, c, in each of said cutters c c, and has an up perbearing in the interior of the cylinder a, and a lower bearing andsupport in the radial slots e in the lower cover, 0, which latter issecured to the lower end of cylinder (4 by means of thehook-s a a asusual, and may be detached from said cylinder a by swinging the hooks abeyond the flange .e on the cover 6.

Within the upper end of the cylinder at is a helical groove, a, which,in combination with the screw-propeller f on the cutter-shaft f, servesto feed the meat toward the cutters, as usual. The shaft f is providedwith suitable means for imparting to it a rotary motion, in a likemanner as shown anddcscribcd in my patent as aforesaid. I

y g g are the rotary cutters, secured to the central shaft, f, in aseries below the screwpropeller f. each of said cutters ghaving rivetedto it a division-block, .g, as shown in Fig. 7, and each cutter g, withits division-block g, is provided with an oblong perforation, g, adaptedto fit the spirally-flattened sides of the cutter-shaft, as usual inmeat cutting'machines.

Below the lowest rotary cutter g is secured on the cutter shaft f theperforated strainerplate 71, having a number of perforations, h h,

or dial being made to rotate with the central shaft, f, and its cutters,it being for this purpose provided with a central oblong hole, h",adapted to'fit the flattenedsides of the shaft f.

-By having said perforated dial revolve it can bemade in a commonturning-lathe, as it is not necessary to have ears or projections on it,as is the case with stationary dials. also be made more cheaply, therebyenabling the purchaser to keep his machine in repair at much less costthan in the old way. Again,

as it revolves with the shaft, there is but little friction comparedtowhat there is when the dial is stationary and the lower knives areattached to the rotary shaft, for in such case it is necessary to crowdthe dial so hard with a as shown in Figs. 2 and 8, such strainer plate1,

nut to keep the revolving knives crowded up to the dial so as to cutstringy meat, and that unless-everything is very carefully adjustedit isvery hard to turn the machine, thereby causing a great expenditure ofpower. The reason that there is less friction by my arrangement is thatthe. meat and dial rotate together, which obviously lessens thefriction.

Above and below the perforated rotary dial or strainer h are located thestationary shearing-knives t t, the edges of which are adapted to lie inclose proximity to the upper and under side of the dial h, for thepurpose of clearing the latter from stringy particles of meat. Each ofthe shearing-knives Z is secured to a stationary block, k, located onone of the spindles d, on which the cutters c c c are held, asv shown inFigs..2 and 3that is, two blocks, 70

7g, with two knives, Z i, one set on top of the dial h, and one set onthe bottom thereof for each spindle d, as shown.

The shearing-knives Z Z are made adjustable to and from the dial h, tocompensate for wear and sharpening by means of set-screws i, passingthrough S1Ot-hO1Gi IIL each knife c, and screwed into the block it, asshown in Figs. 2 and 9. By the use of the slotted knives or blades 1''Z, in combination with the revolving dial h, the blades Z Z can beeasily adjusted at all times so as to fit the dial, and thus more easilycut the stringy meat which may have escaped being cut up by the knivesof the upper part of the machine.

The meat, after being cut by the knives aforesaid, is expelled throughthe opening 6 in the cover 0, and to facilitate the exit of the meatfrom the cylinder a, I secure to the shaft f, below the perforated dial71 the expellersleeve Z, provided on its exterior with a helical orinclined expelling wing, Z, as shown in Figs. 2 and 5. The interior ofthe sleeve Z, or

. knives g g, dial h, and expeller Z Z are all firmly secured to thecentral and rotary shaft, f, so as to partake of the rotary motion ofthe same. It will thus be seen that the expeller Z Z acts not only toexpel the meat, but also as a nut to hold the knives and dial on thecen-. tral shaft, and as the dial is fixed to the shaft the expeller canbe screwed up tight, and thus obtain better results than when leftloose,as is the case with a stationary dial.

e is the lower bearing for the shaft f in the center of the detachablecover 6, and n is a rest or step-piece secured to the cover 0 by meansof screw-bolt n, to prevent the shaft f and its cutters and dial fromsagging downward.

Heretofore in machines of this kind the per forated dial or strainer atthe end of the cylinder has been held stationary, and while in suchposition it is veryliable to become clogged up by the stringy particlesof meat that have passed by the cutters without being disintegrated; butsuch objection is entirely obviated by making the said perforated dialmovable with its shaft, and adapted to move between the cutters Z aboveand below it, causing the stringy particles of meat to be cut up beforepassing by the strainer, and preventing the latter from being clogged upby the meat.

Each spindle d is screw-threaded at or near the place for the lowerblock, k, and there provided with a nut, d, that serves as a support forthe blocks is k and the series of cutters 00, as shown in Fig. 2. Thelower end of each spindle d is reduced at d, which part is in serted inits radial slot 6 in the cover 0, and provided with a hat, (1, on itslower end, below the said cover 6, as shown in Fig. 2, by whicharrangement the said spindles (Z d d, with their knife-holding blocksand cutters, can easily be attached to the cover 6 previous to theirbeing introduced in position within the cylinder a.

What I wish to secure by Letters Patent, and

- cl aim is with stationary blocks 10 k and the adjustable slottedknives i i, as and for the purpose set forth.

2. In a meat-cutting machine, a perforated dial or strainer-plate, h,attached to the rotary cutter-shaft f, and adapted to revolve with it,the adjustable stationary cleaning-knives Z i and blocks is k, incombination with the screwthreaded sleeve Z, with its helical wing Z,substantially as described.

3. In a meat-cutting machine, a series of cutters, 0' c 0, each attachedto a stationary block,

a, and secured in place 011 the respective spin dles d, in combinationwith the cover 6, having radial slots 6 e e for the reception of theWILLIAM G. BELL.
